No account needed · Free forever · macOS 14+

Also in the works: cloud mode — students join from anywhere, even on locked‑down school networks.

For schools & districts →

Type the 6-letter code from your teacher's screen. Or type the full address — like quizblast.net/r/YOURCODE — into your browser's address bar.

One minute, start to finish: set up a game, students join, the board goes up, a phone answers.

The part you'll tell another teacher about

The internet can quit. Your game won't.

The game lives on your Mac, not in the cloud. If the internet dies mid-question, the timer keeps counting and your students stay in. ISP outage, assembly-day overload, rural school — the lesson still happens.

How it works

A real Mac app, not another browser tab.

It runs on your Mac

Your control panel stays on your screen. The game goes to the projector. Two separate windows — students never see your answer key. Sound plays from the Mac's own speakers, right on time, and the game clock runs on your machine so the scoring is always fair.

Students join from any browser

Phones, Chromebooks, iPads — they scan a QR code and they're in. Nothing to install. No account to create. If a student's device drops off Wi‑Fi for a moment, the page reconnects on its own and their score is still there.

The student join page on a phone: name field and the game PIN already filled in from the QR code.

Nothing about students leaves the room

There are no student accounts, so there's no student data to store. Names live in the game for the class period and that's it. Your decks are plain files on your Mac — export them, share them, back them up. Even cloud mode is just a relay: it passes messages and keeps nothing.

The lobby roster: eight first names sorted into four color teams — the only student information the game ever holds.
Game modes

Every mode included. Zero paywalls.

Team play costs extra on other platforms, and a real Jeopardy board usually means juggling a second website. Here it's one app, and all of it is free.

Jeopardy

A full board on the projector. Teams buzz in, with lockouts, just like the show.

Team buzzer

Students answer out loud, you judge. First buzz gets the floor.

Classic quiz

Everyone answers A/B/C/D at once. Speed bonuses optional.

Flashcard race

Auto-advancing cards. Fast and correct earns more.

Spin the wheel

Pick a random student, run eliminations, or load your roster.

Live polls

Ask anything, watch the bars fill on screen. No scoring, no pressure.

Ships with 25 ready-made decks and 8 Jeopardy boards — about 500 questions, kindergarten through 12th grade. Import your own from CSV.

For schools & districts

Built for what actually happens in class.

QuizBlast is built by someone who works in IT for a K‑12 school district — the person whose phone rings when a classroom tool dies mid-lesson. These are the failures that get planned for:

The internet goes out mid-game
The game doesn't use it. QuizBlast runs over your classroom network, on your Mac. The wider internet can die and the game keeps going.
A student's phone drops off Wi‑Fi
The student page reconnects by itself and re-joins with the same name and score. No "ask the teacher to re-add me."
Thirty Chromebooks hit it at once
Measured, not guessed: 1,000 students joined in testing with a 100% success rate and 39 ms average response. Thirty is a quiet day.
The projector setup fights you
The game display is its own window — drag it to the projector and go. Your control panel, with the answers, stays private on your screen.
The school network blocks everything
Heavily filtered or managed networks are what cloud mode is for: students join through quizblast.net instead of your Mac's address. Coming soon.
The district asks where student data goes
Short answer: nowhere. No student accounts exist in any mode. Decks and scores are files on the teacher's Mac. Cloud mode is transport, not a data processor — it stores nothing about students.
Pricing

Teachers already pay for enough.

Who's behind this

Built by the person who gets the help-desk ticket.

I work in IT for a K‑12 school district. When a classroom tool breaks, my phone is the one that rings — so I know exactly how these tools fail: the Wi‑Fi chokes, the filter blocks the site, the free plan ends mid-semester.

I built QuizBlast to be the tool that doesn't do that. It runs on your Mac, so the internet can't take it down. It has no student accounts, so there's no student data to worry about. And the local app is free — really free — because teachers already spend too much of their own money on their classrooms.
